5.4.3 Connecting the PV Array (DC input)
danger
warning
warning
Before connecting the PV array, ensure that the DC switch and AC breaker
are disconnect from the inverter.
NEVER connect or disconnect the DC
connectors under load.
Make sure the maximum open circuit voltage(Voc) of each PV string is less
than 1000Vdc.
Check the design of the PV plant. The Max. open circuit voltage, which can
o
occur at solar panels temperature of -10 C, must not exceed the Max. input
voltage of the inverter.
Improper operation during the wiring process can cause fatal injury to
operator or unrecoverable damage to the inverter. Only qualified personnel
can perform the wiring work.
5.5 Grounding the inverter
The inverter must be connected to the AC grounding conductor of the power distribution grid
via the ground terminal (PE) .
1.Because of the transformerless design, the DC positive pole and DC
negative pole of PV arrays are not permitted to be grounded.

5.6 Grid Type
Based on the local GRID standards, it may select different connection types. In the following
you will find an overview of the most common type of grid structure.
Note: For TT grid structure , RMS voltage between neutral wire and earth wire must be less
than 20V.
